Hilary Duff was hyped as the major guest star on this week's episode of Community, but through no fault of her own, the actress was upstaged by a trampoline.

Indeed, "Aerodynamics of Gender" wasn't the Mean Girls parody I had heard it would be, aside from the simple fact that it featured a few mean girls. But it really featured one mean Abed above all else, and while I can't really get enough of his robotic one-liners, the storyline didn't really offer up anything aside from them.

Except for what I'll refer to as Abed Vision, a visual gag that classified Abed as an actual robot (who watches Cougar Town, if you freeze framed one of the shots) immediately prior to zinging a fellow student. Funny stuff.

Question: did you find Chang funny or annoying? I'm assuming the show made him purposely over-the-top, as some kind of stand-in/mockery of sitcoms with a live studio audience. But I still just thought he was grating.

Moving on, Jeff and Troy's discovery of a Secret Garden-like area alongside Greendale, replete with the world's most tranquil trampoline, stole the episode.

It was just so absurd and so ridiculous and so the kind of thing only Community could pull off. It was also a welcome change to see Jeff not involved in a story that had him rebelling against the group for once.

Quite the opposite, in fact, as he bonded with Troy and found the sort of peace for which Pierce would kill his family. The set-up worked perfectly as a side plot, but then became one of my favorite gags ever when Joshua was revealed to be a racist, culminating in that Swastika tattoo flashback. It's gonna be a maze. I'm still laughing.

Here's a look at the other Community quotes that helped make this episode one of the season's best:

Pierce: Tell me how to get this laid-back, or I'll kill your families! | permalink

Britta: It's called a Muffin Top, Abed.
Abed: Like a muffin. Clever. | permalink

Abed: It's Wednesday. Sometimes I eat in Jeff's car. Don't tell him. | permalink

Britta: Why name your daughter Megan? Are you stocking up for a bitch shortage? | permalink

Britta: Women of Greendale! This cafeteria is hereby declared a bitch-free zone! | permalink

Megan [to Abed]: It's like your mom is a lizard who got raped by a Muppet. | permalink
